Description

Technical Field

[0001] This utility model relates to the field of magnet power supply technology, specifically to a high-frequency switching magnet power supply. Background Technology

[0002] Currently, large-scale superconducting inductor charging uses thyristor-controlled silicon controlled rectifiers to provide excitation current to charge the superconducting coil. During energy discharge, the opening angle of the thyristor is adjusted. However, the power supply efficiency is low and the control and adjustment methods are complex during charging. Adjusting the thyristor during energy discharge is complicated and can easily damage the power supply. Utility Model Content

[0003] In view of this, the present invention provides a high-frequency switching magnet power supply to solve the complex problem of charging and discharging energy through thyristors in the prior art.

[0004] In a first aspect, this utility model provides a high-frequency switching magnet power supply, the power supply comprising:

[0005] A charging module, which is connected to an AC input terminal, is used to receive AC voltage, convert the AC voltage into a high-frequency DC voltage, and then output it.

[0006] An energy dissipation module is connected to both the energy charging module and the superconducting magnet coil.

[0007] When the superconducting magnet coil is charged, the charging module is used to output a high-frequency DC voltage;

[0008] The energy dissipation module is used to transmit high-frequency DC voltage to the superconducting magnet coil;

[0009] When the superconducting magnet coil discharges energy, the energy discharge module is used to dissipate the electrical energy of the superconducting magnet coil and then transmit it to the charging module.

[0010] The charging module is used to receive the lost electrical energy.

[0011] The high-frequency switched magnet power supply provided by this utility model, when charging the superconducting magnet coil, converts AC voltage into high-frequency DC voltage via a charging module, which then charges the superconducting magnet coil via an energy dissipation module. That is, electrical energy is converted into magnetic energy and stored in the superconducting magnet coil. When dissipating energy from the superconducting magnet coil, the superconducting magnet coil forms a circuit with both the energy dissipation module and the charging module, thus converting the magnetic energy in the superconducting magnet coil into electrical energy, which is then dissipated through the energy dissipation module. Furthermore, the three-phase power frequency voltage is converted into a controllable signal with low voltage and high current to provide excitation current for the superconducting magnet, generating a steady-state magnetic field or a magnetic field with a constant rate of change, while simultaneously satisfying demagnetization and energy dissipation after operation. Compared to the traditional method of providing excitation current through transistor thyristors, control and adjustment are simpler, and no adjustment of the thyristors is required during energy dissipation, thus greatly improving convenience. At the same time, integrating charging and energy dissipation significantly reduces the size, facilitating transfer between different devices and allowing installation in devices of various sizes.

[0016] A high-frequency synchronous rectification unit is connected to the high-frequency transformer unit and the energy dissipation module. When the superconducting magnet coil is charged, it is used to convert the high-frequency AC voltage into a high-frequency DC voltage and output it. When the superconducting magnet coil is dissipated, it is turned on and the lost electrical energy is transmitted to the high-frequency transformer unit.

[0017] In one optional implementation, the charging module further includes:

[0018] An electromagnetic interference filtering unit is connected to both the AC input terminal and the bridge rectifier unit. It is used to receive AC voltage and filter out electromagnetic interference from the AC voltage before outputting the voltage.

[0044] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0045] Currently, large-scale superconducting inductor charging uses thyristor-controlled silicon controlled rectifiers to provide excitation current to charge the superconducting coil. During energy discharge, the opening angle of the thyristor is adjusted. However, the power supply efficiency is low and the control and adjustment methods are complex during charging. Adjusting the thyristor during energy discharge is complicated and can easily damage the power supply.

[0046] In this embodiment, a high-frequency switching magnet power supply is provided, such as... Figure 1 As shown, the high-frequency switched magnet power supply includes:

[0047] The charging module 10 is connected to the AC input terminal and is used to receive AC voltage, convert the AC voltage into high-frequency DC voltage, and then output it.

[0048] Energy dissipation module 20, which is connected to the charging module 10 and the superconducting magnet coil respectively;

[0049] When the superconducting magnet coil is charged, the charging module 10 is used to output a high-frequency DC voltage;

[0050] The energy dissipation module 20 is used to transmit high-frequency DC voltage to the superconducting magnet coil;

[0051] When the superconducting magnet coil discharges energy, the energy discharge module 20 is used to dissipate the electrical energy of the superconducting magnet coil and then transmit it to the charging module 10.

[0052] The charging module 10 is used to receive the lost electrical energy.

[0053] Specifically, the charging module 10 receives a high-voltage AC voltage, converts the high-voltage AC voltage into a low-voltage high-frequency AC voltage, and then outputs it to the charging module 10. Optionally, the charging module 10 can be a rectification and high-frequency inverter unit.

[0054] Specifically, the charging module 10 receives a high-voltage AC voltage, converts the high-voltage AC voltage into a low-voltage high-frequency DC voltage, and then transmits it to the superconducting magnet coil for charging. Optionally, the charging module 10 can be a high-frequency power conversion device.

[0055] Specifically, the energy dissipation module 20 dissipates the electrical energy of the superconducting magnet coil. Optionally, the energy dissipation module 20 can be a switching transistor with impedance.

[0056] It should be noted that the high-frequency switching magnet power supply has three states: first, the charging state, i.e., the excitation mode: the control magnet (i.e., the superconducting magnet coil after charging) maintains a stable positive voltage across its terminals, causing the magnet current to rise at a constant rate to the set steady-state operating value; second, the stable state, i.e., the flat-top mode: the operating current remains constant, and the magnet terminal voltage is approximately 0; and third, the demagnetizing state, i.e., the demagnetization mode: the control magnet has a constant negative voltage across its terminals, causing the magnet current to decay to 0 at a constant rate.

[0057] The high-frequency switched magnet power supply provided by this utility model, when charging the superconducting magnet coil, the charging module 10 converts the AC voltage into a high-frequency DC voltage, which is then passed to the energy dissipation module 20 to charge the superconducting magnet coil, i.e., electrical energy is converted into magnetic energy and stored in the superconducting magnet coil. When dissipating energy from the superconducting magnet coil, the superconducting magnet coil forms a circuit with both the energy dissipation module 20 and the charging module 10, thereby converting the magnetic energy in the superconducting magnet coil into electrical energy and dissipating it through the energy dissipation module 20. Furthermore, the three-phase power frequency voltage is converted into a controllable signal with low voltage and high current to provide excitation current for the superconducting magnet, generating a steady-state magnetic field or a magnetic field with a constant rate of change, while simultaneously satisfying demagnetization and energy dissipation after operation. Compared with the traditional method of providing excitation current through transistor thyristors, the control and adjustment are simple, and there is no need to adjust the thyristors during energy dissipation, thus greatly improving convenience. At the same time, integrating charging and energy dissipation greatly reduces the size, making it easy to transfer between different devices and allowing it to be installed in devices of various sizes.

[0058] In some alternative implementations, such as Figure 2 As shown, the charging module 10 includes:

[0059] A bridge rectifier unit 11 is connected to the AC input terminal to receive AC voltage and convert it into DC voltage for output.

[0062] The high-frequency synchronous rectification unit 14 is connected to the high-frequency transformer unit 13 and the energy dissipation module 20 respectively. When charging the superconducting magnet coil, it is used to convert the high-frequency AC voltage into a high-frequency DC voltage and output it. When the superconducting magnet coil dissipates energy, it is turned on and transmits the lost electrical energy to the high-frequency transformer unit 13.

[0063] Specifically, the bridge rectifier unit 11 is used to convert high-voltage alternating current into high-voltage direct current. Optionally, the bridge rectifier unit 11 can be a bridge rectifier, or other devices for converting to direct current.

[0066] Specifically, the high-frequency synchronous rectification unit 14 is used to convert low-voltage high-frequency AC voltage into low-voltage high-frequency DC voltage. When charging the superconducting magnet coil, the high-frequency synchronous rectification unit 14 transmits the low-voltage high-frequency DC voltage to the superconducting magnet coil via the energy dissipation module 20. When dissipating energy from the superconducting magnet coil, the high-frequency synchronous rectification unit 14 is turned on, and the lost electrical energy is transmitted to the high-frequency transformer unit 13. Optionally, the high-frequency synchronous rectification unit 14 is a MOSFET (Metal Oxide Semiconductor Field Effect Transistor) board, composed of multiple MOSFETs.

[0067] In some alternative implementations, such as Figure 2 As shown, the charging module 10 further includes:

[0068] Electromagnetic interference filtering unit 15 is connected to the AC input terminal and the bridge rectifier unit 11 respectively, and is used to receive AC voltage and filter out electromagnetic interference from the AC voltage before outputting it.

[0069] The smoothing filter unit 16 is connected to the bridge rectifier unit 11 and the high-frequency inverter unit 12 respectively, and is used to filter the DC voltage before outputting it.

[0070] Specifically, the electromagnetic interference filtering unit 15 can be a device for filtering out electromagnetic interference. The smoothing filtering unit 16 can be a high-voltage filtering device, that is, it smooths out the sine wave converted from positive voltage.

[0074] When the superconducting magnet coil discharges energy, it outputs energy after energy loss.

[0075] Specifically, when the superconducting magnet coil is charged, the regulating tube 21 is turned on to transmit a low-voltage, high-frequency DC voltage to the superconducting magnet coil. When the superconducting magnet coil discharges energy, the released electrical energy is dissipated. Optionally, the regulating tube 21 is a MOS transistor board composed of multiple MOS transistors.

[0076] In some alternative implementations, such as Figure 2 As shown, the power supply also includes:

[0077] The output filtering unit 30 is connected to the high-frequency synchronous rectification unit 14 and the regulating tube 21 respectively. The output filtering unit 30 is used to filter the output high-frequency DC voltage before outputting it.

[0078] Specifically, the output filtering unit 30 is used to receive the low-voltage high-frequency DC voltage transmitted by the high-frequency synchronous rectification unit 14, and transmits the low-voltage high-frequency DC voltage to the superconducting magnet coil after filtering, thereby improving the stability of transmitting high-frequency DC voltage.

[0079] In some alternative implementations, such as Figure 2 As shown, the power supply also includes:

[0080] A first trigger control board 51 is connected to the high-frequency synchronous rectification unit 14 and is used to receive a first control signal and control the high-frequency synchronous rectification unit 14 based on the first control signal.

[0081] A first logic control system 52 is connected to the first trigger control board 51 and is used to receive a first logic signal locally or remotely and send a first control signal of the first logic signal to the first trigger control board 51.

[0082] Specifically, the first trigger control board 51 is used to control the high-frequency synchronous rectification unit 14, and the first logic control system 52 can receive the first logic signal sent by the local control system and also receive the first logic signal sent by the remote control system. It can be understood that the first logic control system 52 is a charging control system.

[0083] In some alternative implementations, such as Figure 2 As shown, the first trigger control board 51 is connected to the output filter unit 30 and is used to collect the high-frequency DC voltage filtered by the output filter unit 30, and adjust the first control signal based on the filtered high-frequency DC voltage.

[0084] Specifically, the filtered high-frequency DC voltage output by the output filter unit 30 is transmitted to the first trigger control board 51 to perform DC feedback, thereby forming a closed loop with the high-frequency DC voltage output by the high-frequency synchronous rectification unit 14, which in turn improves the accuracy of charging the superconducting magnet coil.

[0085] In some alternative implementations, such as Figure 2 As shown, the power supply also includes:

[0086] The second trigger control board 53 is connected to the adjustment tube 21 and is used to receive the second control signal and control the adjustment tube 21 based on the second control signal.

[0087] The second logic control system 54 is connected to the second trigger control board 53 and is used to receive local or remote second logic signals and send the second control signals of the second logic signals to the second trigger control board 53.

[0088] Specifically, the second trigger control board 53 is used to control the adjusting tube 21, and the second logic control system 54 can receive the second logic signal sent by the local control system and also receive the second logic signal sent by the remote control system. It can be understood that the second logic control system 54 is an energy leakage control system.

[0089] In some alternative implementations, the first logic control system 52 is communicatively connected to the second logic control system 54.

[0090] Specifically, when the superconducting magnet coil discharges energy, the first logic control system 52 sends a first logic signal to the first trigger control board 51, causing the high-frequency synchronous rectification unit 14 to operate. Then, it communicates with the second logic control system 54 and sends a signal, causing the second logic control system 54 to control the adjustment tube 21 to turn on. When the superconducting magnet coil discharges energy, the second logic control system 54 turns on and then communicates with the first logic control system 52, causing the first logic control system 52 to turn on. At this time, the electrical energy of the superconducting magnet coil returns to the superconducting magnet coil through the adjustment tube 21, the high-frequency transformer unit 13, the high-frequency synchronous rectification unit 14, the output filter unit 30, and the adjustment tube 21, forming a loop, and losing energy during the turning on of the adjustment tube 21. The first logic control system 52 and the second logic control system 54 are each connected to a host computer. By independently setting the first logic control system 52 and the second logic control system 54, and by controlling both the first logic control system 52 and the second logic control system 54 as a whole through the host computer, convenience is greatly improved.

[0091] It should be noted that the charging and demagnetizing processes are made into two parts and connected in series in a single power system for independent control. Within the device, charging uses a high-frequency synchronous switching power supply, while demagnetizing uses an adjustment tube. The working state of the adjustment tube is controlled by a logic control system to achieve the goal of rapidly releasing the magnetic energy in the superconducting magnet into electrical energy within a certain time frame, while ensuring safety and reliability. This energy is then consumed by the adjustment tube.

[0092] In some alternative implementations, such as Figure 2 As shown, the power supply also includes:

[0093] A control transformer 60 is connected to the smoothing filter unit 16, the first trigger control board 51, and the second trigger control board 53, respectively, and is used to supply power to the first trigger control board 51 and the second trigger control board 53, respectively.

[0094] Specifically, the control transformer 60 receives the voltage filtered by the smoothing filter unit 16 and transmits it to the first trigger control board 51 and the second trigger control board 53 respectively, thereby supplying power to the first trigger control board 51 and the second trigger control board 53.

[0095] It should be noted that in the charging state, AC power is converted into DC power output to charge the superconducting magnet coil. The three-phase AC power is converted into DC power and stored in the superconducting coil in the form of magnetism to meet the magnetic field requirements of the superconducting device during operation. At this time, the adjustment module filters the current during the steady-state operation of the high-frequency switched magnet power supply. After the superconducting device finishes working or when operation ends, the huge amount of energy in the superconducting magnet coil needs to be released to protect the inductor and avoid impacting the power grid. At this time, the power supply switches to the demagnetizing state. Through the control system, the adjustment tube is turned on and the charging module is turned off to demagnetize the superconducting magnet coil. This provides a demagnetizing load for the demagnetizing operation, reduces the damage rate of the superconducting magnet inductor, and provides an effective solution for the construction of the demagnetizing device in areas with weak power grids.

[0096] It meets the need for flexible operation under different working conditions and requirements, allowing the device to operate in multiple modes and control methods. High-frequency switching power supplies offer advantages in cost and efficiency compared to transistor thyristors, and also have advantages in demagnetization. Due to its small size, it can be easily transported and installed in different workplaces.
